\ This invention f relates to ,devices attach` able to carburetors for openingadj'ustment. Such a device iinds employment Where a linnen7 automobile is td-beifdelivered from the manufacturer toa dealer by drivingthevelimiting t throttlev hicle overlandfunderitsown povveri *It ishighly essential. `that operation of aI nevvly Y assembled vehicle be at lovv speeds-until the 1 parts are'sufliciently runin7 to maketheml Work freely* together, and much damagev Will be the immediate result 'ofioverspeeding Within lthe iirstfetv hundred miles of driv` ing. The drivers of vehicles thusbeing delivered overlandf are, of a.' relatively irrei. sponsibleand none too intelligent, and some'-, times unscrupulous class; so that it becomes imperative that means be provided for posi- Vtively preventing overspeeding during de- 0 livery. f

The object of .the present invention then Y is to provide ade-vicevvhich maybe conveniently attached. to the carburetor of` a new, vehicle at-the factory; may be there sealed as ,well as, secured in positiontopositiv'ely limit the throttle-openingadjustment, so`

that the speed yofthe engine and hence that of the :vehicle is t correspondingly limited ;y

and Amay be as conveniently 'detached rby is delivered; .t

' Experience has taught Vthat many ingenuous expedients Will be attempted to yrender f; such 4a device when attached, inoperative for its intended purpose, and it is the further object of this invention to'make the device thoroughly protective against 'unauthorized tampering. l l Further objects ofv the detailsfof construction to this end, Whichare hereinafter i set forth.
